United Nations reach landmark agreement to protect ocean life

An agreement to protect marine life in the regions outside national boundary waters, known as the high seas, had been discussed for more than 20 years.

A HISTORIC AGREEMENT to protect the world’s oceans has been reached following years of negotiations.

For the first time, United Nations members have agreed on a unified treaty to protect biodiversity in the high seas – nearly half the planet’s surface.

The UN Convention on the Law of the Sea came into force in 1994, before marine biodiversity was a well-established concept.

An updated framework to protect marine life in the regions outside national boundary waters, known as the high seas, had been discussed for more than 20 years, but previous efforts to reach an agreement had repeatedly stalled.

The unified agreement treaty was reached late last night after two weeks of talks in New York.

“We only really have two major global commons – the atmosphere and the oceans,” said  marine biologist Rebecca Helm.

While the oceans may draw less attention, “protecting this half of the Earth’s surface is absolutely critical to the health of our planet”, she added.

Now that long-awaited treaty text has been finalised, Nichola Clark, an oceans expert at the Pew Charitable Trusts who observed the talks in New York, said: “This is a once in a generation opportunity to protect the oceans – a major win for biodiversity.”

The treaty will create a new body to manage conservation of ocean life and establish marine protected areas in the high seas.

Clark said that is critical to achieve the UN Biodiversity Conference’s recent pledge to protect 30% of the planet’s waters, as well as its land, for conservation.

The treaty also establishes ground rules for conducting environmental impact assessments for commercial activities in the oceans.

“It means all activities planned for the high seas need to be looked at, though not all will go through a full assessment,” said Jessica Battle, an oceans governance expert at the Worldwide Fund for Nature.

Many marine species – including dolphins, whales, sea turtles and many fish – make long annual migrations, crossing national borders and the high seas.

Efforts to protect them – and human communities that rely on fishing or tourism related to marine life – have previously been hampered by a confusing patchwork of laws.

“This treaty will help to knit together the different regional treaties to be able to address threats and concerns across species’ ranges,” said Battle.

That protection also helps coastal biodiversity and economies, said Gladys Martinez de Lemos, executive director of the non-profit Interamerican Association for Environmental Defence, which focuses on environmental issues across Latin America.

“Governments have taken an important step that strengthens the legal protection of two thirds of the ocean and with it marine biodiversity and the livelihoods of coastal communities,” she said.

The question now is how well the ambitious treaty will be implemented.

The high seas have long suffered exploitation due to commercial fishing and mining, as well as pollution from chemicals and plastics.

The new agreement is about “acknowledging that the ocean is not a limitless resource, and it requires global co-operation to use the ocean sustainably,” said Malin Pinsky, a biologist at Rutgers University in the US.
